Installation SPIDER II 16TX
Release 02 12/2014

Supply voltage
The supply voltage is electrically isolated from the housing.

Ground the device before connecting any other cables.

Connect only a supply voltage that corresponds to the type plate of
your device.

Every time you connect the electrical conductors, make sure that the
following requirements are met:

The voltage supply conforms to overvoltage category I.
 The power supply has an easily accessible disconnecting device
(e.g., a switch or a plug). This disconnecting device is clearly iden-
tified. So in the case of an emergency, it is clear which discon-
necting device belongs to which power supply cable.

The electrical wires are voltage-free.

Relevant for North America:
The power supply is Class 2 compliant.
 The supply voltage inputs are designed for operation with safety
extra-low voltage. Connect only SELV circuits with voltage restric-
tions in line with IEC/EN 60950-1 to the supply voltage connec-
tions.
 A fuse suitable for DC voltage is located in the plus conductor of the
power supply.
Regarding the properties of this fuse:
See “General technical data”
on page 22.

The wire diameter of the power supply cable is at least 1 mm²
(North America: AWG16) on the supply voltage input.
 The power supply cables used are permitted for the temperature
range required by the application case.

Relevant for North America: For use in Class 2 circuits
Use copper wire/conductors of class 1 60/75 °C or 75 °C or 90 °C
exclusively.

Installation site requirements

Verify that there is at least 4 in (10 cm) of space above and below the
device.

Verify that there is at least 0.8 in (2 cm) of space on the right and left
sides of the device.

Only install the device in “operating sites with restricted access” based
on EN 60950-1.
